Change the mechanism of enabling the force PWM mode through
regulator set mode. This can be dynamically configured now.
In the REGULATOR_MODE_FAST the force PWM is enabled and in
REGULATOR_MODE_NORMAL the force PWM is disabled.

This will avoid the copy of entire regualator init data into

A lot of regulator hardware maps selectors on to voltages with a simple
linear mapping function

    selector = base + (selector * step size)

Provide off the shelf list_voltage() and map_voltage() operations which
use new min_uV and uV_step members in the regulator_desc to implement
this function.

In order to allow more drivers to factor things out into data allow
drivers to provide a mapping function to convert voltages into selectors.
This allows any driver to use set_voltage_sel(). The existing mapping
based on iterating over list_voltage() is provided as an operation which
can be assigned to the new map_voltage() function though for ease of
transition it is treated as the default.

Merge remote-tracking branches 'regulator/topic/core', 'regulator/topic/regmap' and 'regulator/topic/register' into regulator-next

The core really wants a struct device to be supplied for regulators and

The regulators in the twl4030 can provide some voltage settings
that are not offically supported.
These settings are disabled by default, but can be enabled with
  CONFIG_TWL4030_ALLOW_UNSUPPORTED=y
However
 - that config variable is not mentioned in any Kconfig so cannot
   be used, and
 - a global setting is clumsy - a per regulator setting would be
   better.

So define a new 'feature' flag that a board file can set to enable
these unsupported volatages for boards which need them.

This flag cannot (yet) be set using device-tree.

twl-regulator has a collection of feature flags, some defined
in twl-core.c and  one defined in i2c/twl.h.
This is confusing for anyone adding a new feature flag.

So collect them together and place them in twl.h immediately
after the structure in which they are initially set.

- The print message should be not break into multiple line.
- line gap after variable declaration and statement.
- checkpatch error.
- some typo.

also along with proper text.

Avoid voltage_base conversion to microvolts every time.
Put init functions in init section.
